AODE (2-Pack, Black & Yellow) Digital Fish Tank Aquarium Thermometers 600012

Good for the money. Only downside is the stoppers keep falling off and I actually lost one the same day! :(

Love them both. Use it for my little aquaponic tank.

The yellow one arrived DOA and the black one works great. Thought I was getting a deal... Oh well.

buy them there small and right with dual suction cups to install on the side out of the way its great

Both read within half a degree. Very nice accuracy from such an inexpensive product

Lcd screen is to small making it hard to read or see.

They are good and accurate I have one of those in each of my fish tanks.

Great deal 2 for 1. Work flawlessly
